Abstract
An apparatus for regulating the flow of a fluid from a source to a target location comprises a housing defining a fluid inlet configured to communicate with a fluid source and a fluid outlet configured to communicate with a target location, and a flow path extending between the fluid inlet and fluid outlet. An inlet valve assembly is mounted in the flow path and comprises a valve seat and a valve member configured to cooperate with the valve seat to regulate flow through the flow path. A balance arrangement is provided and is configured to balance the effect of fluid pressure acting on the inlet valve assembly.
